Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.

I like it, Nice.
For Alien defense I use my Cateye TL-LD1000/with laser beam to blast them out of the sky.
This will severly effect your batteries life. So only use when needed. :)

The pure green tractor beams are anti-grav based and require two contact points on the ground to form a complete grav/anti-grav circuit. Pedrestrians are vulnerable, except when running, which is why they sometimes use stun rays in addition to the tractor beam. My method is to wheelie or manual to deprive them of the second contact point. The aluminum frame of the bicycle absorbs all of the energy from the stun rays.
The turquoise green tractor beams, which are less expensive and therefore more common, operate on the principle of electromagnetics, so this guy's method works against those:
A 3v lithium cell concealed in the rear hub creates an electromagnetic field in the spokes, which are distributed tangentially and can interfere with most types of tractor beam. The polarisation of these waves depends upon the amount of wheel dish and the lacing pattern. Shorter spokes throw off a larger field, but longer spokes throw it further. Double butted spokes have the advantage of a variable magnetic field along their length, which really fools the aliens! Try to ensure that your wheel's angular velocity is such that the EM waves are in antiphase which the tractor beam... a selection of close ratio sprockets should help. You are aiming to give off waves that are a multiple of the wavelength of green light (405nm?).
I do have to correct him on one minor point. We're working with turquoise green, so you actually want a multiple of 404 nm. It's very minor, really, and within the margin for error in your cadence.
